When I open the Mozilla VPN window I am met with the "Get Started" page. I click the "Get Started" button and sign in. When I get to the "Signed in successfully!" page, it tells me to open the Mozilla VPN window again (it does this for me) and to turn it on and all that. However, when the window is opened again, I am met with the same "Get Started" page from the beginning, leaving me in the endless loop of logging in. I am running a fully updated Windows 11. Could it be an extension I have?

I am experiencing significant stability issues with Firefox. When I use YouTube, the entire browser frequently hangs (becomes unresponsive) and eventually crashes. This does not happen on all websites, but it is consistent when playing video content on YouTube.

  • Symptoms: The browser "stacks" or freezes completely; I cannot click tabs or menus until the browser finally closes/crashes.
  • Extensions: I am currently using extensions like SponsorBlock, uBlock origin. I am unsure if this is the cause, but the issue persists during video playback.
  • Hardware: I am running this on a laptop with an 16gb 4800mhz RAM, i7 12th Gen processor and an RTX 3070 GPU.


  1. Is there a known compatibility issue between current Firefox builds and SponsorBlock or similar video-modifying extensions?
  1. Could this be related to hardware acceleration settings with my NVIDIA GPU?
  1. What steps should I take to provide crash logs to help identify the root cause?

I'm really stumped and confused why this would be, but, I'm unable to sign in to my account on one of my devices, though I can access it from other devices.

I have a work computer and a personal computer. I want to have a profile on my personal computer signed into a an account I share on my work computer so I can easily access tabs and history across my these to devices that's separate from my main firefox account attached to my personal email. Got the profile signed in on my personal computer, went to sign in on my work computer and got a message "unexpected error." I attempted to disable the extensions and clear cache at the advice of one thread I saw from years ago but I really have had a heard time finding anyone with this issue at all.

Anyway, any help would be appreciated! Thanks!

I clicked on auto restore previous session about six months ago. The session I had open that day of about 20 (now completely irrelevant) tabs opens every time I open my browser. I have to close them all to start a new work day.

I found a work- around. If I go to History and clicking on Restore Previous Session within the History setting yhis took me to my last session. Now the browser is starting to add additional tabs I had open during that previous day. This is a nightmare - I never have a clear browser. How to stop this? I use my History. I don't want to delete History and clear all of the cache and the browser memory. I have put in a request for help before 2-3 months ago. That was the only suggestion. Some idiot invented this option. The same idiot needs to work out how to fix this bug. (apologies to the volunteers who read this - I appreciate your thoughts).

As it says in the subject title. After performing a search and executing it. A new tab opens that displays about:blank. This occurs everytime an serach is performed the first time when opening Firefox. My current home page is set to Yahoo.com but will happen using any search engine.

When the tab is closed and the search is initiated again on the initial page. The search results populate. This is persistent and repeatable. This has happened since the previous update from the current version 149.0,2 on a Windows 11 pc.

The same thing happens on another pc that I use. And started happening without any prior glitches.

I have hased this question with no response since noticing the issue using the previous version.

Also. I have tried online suggestions to repair the issue with no positive results.

Needing a rapid fix.

I had recently tried to download a .Zip file, which got corrupted. I tried twice again. Now every time I open the browser the three corrupted files pop up in the "downloads" window. It does not appear when opening a new tab, only when starting the browser. I have deleted the corrupted folders and don't want to retry downloading. I have tried both "clear all downloads" and "remove from history" in the downloads window, but the notification still shows up. Settings do not help.

How can I remove this pop-up? It blocks my toolbar and is a general nuisance.

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

I've tried to find a way to fill the webpage to fit within my screen size without luck. I always need to scroll to the right to view the extra content. Is there a method to view the webpage within my screen size..?

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?
